Two questions.
The goal of the referendum is to force the government to reject it, or to force the government to accept it?
The rejection of them would be YES or NO on the ballot?
The primary goal of the referendum is to let the people have the final say on the tax deals, with the ultimate goal being that the tax deals will be rejected.
In order to avoid the kind of confusion you mentioned, the questions on the ballot will fortunately be presented in the most straightforward way possible, probably like this:
- Do you approve of the tax deal with Germany/Austria/the UK (each question will be asked separately)?
A YES vote means you approve of the tax deal in question, a NO vote means the opposite.
